Today Wordpress notified me of a pingback on one of my posts.
It appears someone has copied and pasted the first paragraph of one of my posts and put it on their own blog with a link to my post so the reader can read more than just the first paragraph.
What does all of this mean ?
What will "approving" the pingback do for me if anything ?
From first sight this looks good. I just got a backlink from someone for free. Which begs the question "why would someone copy paragraphs from others blogs and post it on their own blog?" - surely this is duplicate content which google hates ?
Thank you in advance for your explanations and advice
